How to fix machine error AF on Brother printers

The scanner flat cable has to be reconnected to the main pcb.


- Open the printer scanner cover as you would do to change the carts.
- Unlock the blue support and lean the scanner towards a support ("L") open the small cover which will be found in the middle and goes to the left side.
- Beneath that is a white flat cable which simply has to be fixed into the main circuitboard (= pcb = printer circuit board).
